#Jacoco report file how to#If you’re in a hurry, here’s how to configure the Gradle adle build script to integrate with Jacoco and SonarQube for unit tests only. The code coverage results can be viewed on the Overview tab of the Build Results page detailed report is displayed on the dedicated Code Coverage tab. If you haven’t tried out this approach yet, then I suggest first reading How to Measure Code Coverage Using SonarQube and Jacoco which explains the step-by-step process. Check that your classfiles are compiled with debug information (including the source file info) to see with highlighted source code in the report. The data can then be published to the static analysis tool SonarQube via the sonarqube plugin. JaCoCo is a free code coverage library for Java, which has been created by the EclEmma team based on the lessons learned from using and integration existing libraries for many years. Generating code coverage data based on unit tests is straightfoward in Gradle thanks to the jacoco plugin. Jacoco is a tool which generates such metrics. Code coverage for unit testsĪ code coverage metric tells you what percentage of your proudction code is covered by tests. It also includes functionality to include columns in Dashboards which displays the latest overall coverage numbers and links to the coverage report. Jenkins will generate the trend report of coverage and some other statistics. The configuration for the JaCoCo and Surefire Maven plugins was set up such that on-the-fly. This plugin allows you to capture code coverage report from JaCoCo. Code coverage dropped There wasn't a reduction in tests so something else must have been at fault. But how do you generate a combined code coverage metric? In this article you’ll discover exactly how, with a full example project which publishes Jacoco code coverage stats to SonarQube. We make heavy use of PowerMock in many of our JUnit tests and recently as we switched from Cobertura to JaCoCo something strange happened. It’s hepful to separate integration tests from unit tests in a Java project to run them independently.
